@wzg69g, if many other students in his class do turn in assignments on time and properly follow all instructions on assignments and exams, leading them to have higher GPAs than your son, the admissions officers will be 100 percent justified in looking down on your son’s lower GPA. You obviously want sympathy and assurance that the teacher is being unfair to your son, but everything you’re describing sounds like a normal AP class which has higher expectations for students’ maturity and time management skills.
